over the past 2 years ive been getting the hunger to backpack, ive finished my 2nd year at uni and am planning to hit the AT once im done, maybe if i get a job & sabbatical from it, or in between undegrad / grad school. how do i transition from day-hiking to backpacking? how do i train for it? i spend most of my days outdoors, away from people & the comforts of my home already.
